How many of you know that this region in the Northern Hemisphere is considered as the Death Valley of Russia?! Why? Well this is the infamous region where Russia conducted innumerable number of nuclear tests. When you check the history of this region you would be shocked that even Tzar Bomba was dropped here. Yep Tzar Bomba was the biggest ever nuke dropped with its mushroom cloud rising upto 60 kms!! The explosive power was reduced from 100 Mega Tons to 50 Mega Tons. Compare that with Hiroshima which was a meagre 13-16 Kilo Tons!!
